In addition, the terms “first”, “second” and “third” are only for the purpose of description, and may not be understood as indicating or implying the relative importance.

One specific implementation of the present disclosure provides an air pump device. As shown in FIG. 1 to FIG. 3 , the air pump device includes a housing 10, and a circuit board 20, a battery 30, a high-pressure air pump 40 and a low-pressure air pump 50 which are arranged in the housing 10. The high-pressure air pump 40 and the low-pressure air pump 50 are connected with the same public pipeline 60. An air pressure sensor (not shown) is arranged at the public pipeline 60, and is used for monitoring an air pressure inside the public pipeline 60. A display screen 11 and functional buttons 12 are arranged on the housing 10. The display screen 11 and the functional buttons 12 are connected with the circuit board 20. Working modes, an inflating volume and the like of the air pump device can be selected through the functional buttons 12.

The high-pressure air pump 40 is a reciprocating air pump, and includes a motor 41, a piston tube 42 and a piston; the piston is arranged in the piston tube 42; the motor 41 is used for driving the piston to move in the piston tube 42; an output shaft of the motor 41 is perpendicular to an axial direction of the piston tube 42; and an air outlet end of the piston tube 42 is connected with the public pipeline 60, and the piston tube and the public pipeline 60 are parallel or located on the same straight line. In the figure, the public pipeline 60 and the piston tube 42 are on the same straight line.

The low-pressure air pump 50 is a blowing-type air pump, and includes a shell and a fan assembly; one end of the low-pressure air pump 50 is connected to a side wall of the public pipeline 60; and the low-pressure air pump 50 and the motor 41 are parallel to each other and are located on the same side of the public pipeline 60.

One end of the public pipeline 60 opposite to the high-pressure air pump 40 extends to the housing 10 to form a first air port 61. The other end of the low-pressure air pump 50 extends to the housing 10 to form a second air port 51. The first air port 61 and the second air port 51 can be externally connected with pipelines.

The air pump device includes a high-pressure mode, a low-pressure mode and an air suction mode. The high-pressure mode and the low-pressure mode are inflating modes.

Specifically, in the low-pressure mode, the high-pressure air pump 40 does not work, and the air pressure may not work, either. The low-pressure air pump 50 works and inflates the public pipeline 60.

In the high-pressure mode, the low-pressure air pump 50 first works and inflates the public pipeline 60. When the air pressure sensor monitors that an air pressure value in the public pipeline 60 is greater than a preset pressure value, the low-pressure air pump 50 stops working, and the high-pressure air pump 40 is started to work; and the preset pressure value is M times a maximum air pressure value that can be achieved by the low-pressure air pump 50, and M is less than 1. The low-pressure air pump 50 adopts the blowing-type air pump. In a low-pressure environment, the inflating volume per time of the blowing-type air pump is greater than the inflating volume per time of the reciprocating air pump. Therefore, in the early stage of inflation, when an internal air pressure of an inflated device is relatively low, the blowing-type air pump is first used for inflation to increase the inflating speed. In the later stage of inflation, the internal air pressure of the inflated device is relatively high, the blowing-type air pump cannot inflate the device to a high pressure. The reciprocating air pump is used to ensure the inflating pressure.

In a specific implementation, the M is between 0.6 and 0.8. Preferably, the M is 0.7, and the maximum air pressure value that can be achieved by the low-pressure air pump 50 is 1 PSI (Pounds per square inch). According to the study of the inventor, the low-pressure air pump 50 with the maximum air pressure value of 1 PSI is used, and M is set to be 0.7. Specifically, at this time, the low-pressure air pump 50 works to increase the pressure to 0.7 PSI. When the air pressure sensor monitors that am air pressure value in the public pipeline 60 is greater than 0.7 PSI, the low-pressure air pump 50 stops working, and the high-pressure air pump 40 starts to work. In this case, the time for inflation is the shortest, that is, the inflation is the fastest.

In the air pumping mode, the high-pressure air pump 40 does not work, and the low-pressure air pump 50 reversely pumps the air out of the public pipeline 60. The blowing-type air pump is used for inflating equipment, so that the air pumping speed is higher. The low-pressure air pump 50 is multifunctional, which can realize an inflating function or an air pumping function.
